Overtime Review 2026: On-Chain Sportsbook With No KYC

Overtime, also branded Overtime Markets, is a decentralized sportsbook that runs on smart contracts. DefiLlama files it under prediction markets and describes it as an ecosystem for sports betting and digital options trading, with Chainlink data feeds and liquidity pools. It lists deployments on Arbitrum, Base, Optimism, Polygon, Ethereum and BNB Chain, and an OVER token.

The pitch is simple: connect a wallet and bet, with no account, no KYC and no limits on winners. The homepage says everything is automated through smart contracts, so there are no sharp bans and payouts happen on-chain.

Total value locked is about $1.25M, down 2.7% over the last seven days. That is a small base compared with large DeFi protocols, and it is the pool that backs the bets. DefiLlama lists two audits, though the project does not say who did them.

Much of the homepage reads as general advice on crypto sports betting. Treat its claims, such as having the widest offering anywhere, as marketing rather than verified fact.

Overtime is a sportsbook run by smart contracts instead of a company holding your balance. You connect a wallet, pick a market and place a bet from your own funds. The contract records the bet and later pays out according to the result.

According to DefiLlama, the platform uses an AMM architecture and trustless liquidity pools. In simple terms, liquidity providers deposit funds into pools that act as the counterparty to bettors, and the pricing logic sets the odds. Chainlink data feeds supply sports data so results can be settled without a central operator deciding the outcome.

Because settlement is on-chain, bet tickets and payouts are visible on a block explorer, which is the transparency the site stresses. The homepage describes winnings as claimable in your profile.

Overtime's fees are not published, so we cannot state a margin, vig or protocol fee. Odds on an AMM-based sportsbook already include the pool's pricing, so compare the quoted odds against other books.

You will also pay network gas on whichever chain you use, and any exchange or bridge costs to obtain your betting coin. The homepage claims low fees on crypto transactions, but gives no figures. Check the odds and any fee line shown on the betting slip before confirming a bet.

Overtime is non-custodial, so you keep your keys and the platform does not hold a balance for you. The main risks are smart-contract bugs, oracle or data-feed problems, and thin liquidity. DefiLlama lists two audits, but an audit lowers risk without removing it, and the project does not include audit reports or incident history.

Public sources name no gambling licence or regulator, and the platform says it has no KYC. That means no regulator oversight and probably no formal dispute route. Online gambling is restricted in many places, so check the law where you live and do not try to evade geo-restrictions or age checks. You must be 18 or older. Set deposit limits, never bet money you cannot afford to lose, and seek help if gambling stops being fun.

Overtime is for crypto-literate bettors who already use self-custody wallets and want transparent, on-chain sports betting without an account. It is a poor fit for beginners who are unfamiliar with gas fees, networks and wallet security, and for anyone who needs licensed-operator protections or lives where online gambling is restricted.
